How do I check if a CGPoint has been initialised?

Question

I would like to initially set a CGPoint property to a particular point (middle of screen). Other methods may subsequently wish to change this property. My thoughts were to initi

Answer 1

Create two CGPoint properties, that way they are both "uninitialized". Set one of them and use the second one to check whether or not they are equal.

@interface ClassName ()

@property (nonatomic) CGPoint point1;
@property (nonatomic) CGPoint point2;

@end

@implementation ClassName

self.point1 = CGPointMake(69.0f, 180.0f);  //arbitrary numbers

  //if not equal, then if statement proceeds
if (!CGPointEqualToPoint(self.point1, self.point2) {
    //your code here
}

@end

Idk if you'd consider this way hackish though. And I know your question was already answered, but I had kinda the same dilemma till I thought of this.
